When attempting to solve string theory equations, if one equation doesn't result in something which agrees with experimentally proved fact, than it is said that this must apply to another universe, and another version would surely work in ours. The only proof that is provided behind this idea is the anthropic principle. This basically means that since we're here and alive, there must be a version of the equations which work. However, so many assumptions are made in the theory that this is more of a leap of faith than science. And since any version could be true, string theory loses all predictive power in our universe, and so one is left to wonder what use it has.

While the author is not afraid to go after the current direction of physics, and point out what he thinks is wrong, he also shows much praise to those who are espousing these wrong views. He goes to some length to explain the new directions and discoveries that have been made in advanced mathematics that have come as a direct result of investigating string theory. Although he feels that string theory itself if a bust, much of the math that has come about attempting to prove string theory could lead to new discoveries in and of itself. This may be the saving grace that string theory has in the annals of history.

The last chapters attempt to explain why so many scientists refuse to accept that string theory is a failed idea. The author provides some very interesting insight into the current state of academic achievement, grant programs, and peer pressure. Like the old gambler who constantly loses at the poker tables, and is told that the tables in the city are rigged, many physicists continue to examine string theory because they say "it's the only game in town."

In essence, because so many people have invested in it with their careers and their pride, many are simply passing the buck, and waiting for someone else to explore new waters. A few theories are trying to make their way into the fold, and Woit briefly explains a few of them, but only about one chapter is devoted to the subject. What he does provide throughout the book however, are the names of other well known books in each subject he discusses for those who want even more in-depth knowledge than he is willing to provide here.

In the end, Not Even Wrong gives an interesting counterpoint to several other books that have made string theory accessible and popular in the public mind, including Brian Greene's The Elegant Universe. The first half of the book can be hard to understand, but that doesn't detract from the overall theme of the book, though it can make it a difficult read at times.
